add instructions for uploading local files to new VM
one of the first things a new VM user might need to do is upload files to the new VM. I had to dig deep and succeeded only in setting up RDP (by installing Xrdp on the vm); but that option has two problems:
1) this works only with a password (so don't deploy the vm with the default azureuser and key)
2) setting RDP to include local files does not give permission the logged on user to access the local files
the workaround for 1 if you setup azureuser with a key is to add a user with a password
the workaround for 2 is to copy/paste.
